Need help on Bar Chart Auto Binding

[cindy]

Hi,

I'm using MVVM auto binding to create a Bar Chart

in my xaml,

 

<telerikChart:RadChart Width="200" Height="200" ItemsSource="{Binding DisplayedCapacitySeries}" Padding="3">
....
 <telerik:SeriesMapping.ItemMappings>
    <telerik:ItemMapping DataPointMember="YValue" FieldName="Capacity_TB"/>
     <telerik:ItemMapping DataPointMember="XCategory" FieldName="CapacityName" />
 </telerik:SeriesMapping.ItemMappings>

The chart was created at the first loading. However, the Chart is not refreshed when Caparity_TB is changed although INotifyPropertyChanged is implemented in the ViewModel class. 

Also I want to show the legend with the CapacityName. I'm using LegendDisplayMode="DataPointLabel". However, the legend shows as "item 0 .. item 1" instead of the CapacityName on the XCategory.

Also how can I hide the legend header? 

 

Thanks,

[Ves]

Hello cindy,

Please, find attached a small example, showing this scenario. For the legend items, you need to add another ItemMapping where with DataPointMember=LegendLabel. Finally, setting the ChartLegend.Header to string.empty will make it disappear.
